' CIRCULAR BUILDING Filed April 25, 1946 3 Sheets-Sheet 3 Patented Feb.26, 1952 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to a circular building for storage, and other uses.

Among-objects of this invention is to provide a circular building forstorage, living purposes, or shelter. plane hangar and has turnablemeans therein for the quick entry and removal of airplanes, and isadapted to hold the maximum number of airplanes for the space. Wconstruction is substantial, yet economical of manufacture, is simple toassemble, is elficient in use, and lasting in wear.

My invention also contemplates such other objects, advantages, andcapabilities which are inherently possessed by my invention and whichwill later more fully appear.

While I have shown in the accompanying drawings a preferred form of myinvention, yet I wish it understood that the same is susceptible ofmodification and change without departing from the spirit of myinvention.

Referring to the drawings, Fig. 1 is a top plan view of my circularbuilding; Fig. 2 is a front elevational view; Fig. 3 is a frontelevational view with part of the roof removed to show the truss; Fig. 4is a side elevational view with parts broken away to show the connectingbrace from center to circumference; Fig. 5 is a detailed sectional viewof the door and rail construction; Fig. 6 is a detailed assembly view ofone of the roof segments; Fig. '7 is a detailed sectional view of myinverted roof connecting strip; Fig. 8 is a detailed sectional view of amodified strip; Fig. 9 is a detailed floor plan of my circular hangar;Fig. 10 is a detailed enlarged sectional View of my turntable; Fig. 11is a top plan view of a part of the turntable; Fig. 12 is an end view 1of my dolly; Fig. 13 is a top plan view of my dolly; Fig. 14 is adiagrammatic view of an airplane in position on my dollies; Fig. 15 is adetailed view of my bracket to tilt the planes; Fig. 16 is a sectionalview of my continuous dolly; and Fig. 17 is a detailed sectional View ofmy continuous dolly.

The embodiment selected to illustrate my invention comprises a pluralityof upright sections of corrugated metal, or other suitable material, thebottom edges of which are supported on the round or other base to formthe sidewalls I ll of a circular building II. Substantially in thecenter, within the walls, is upright center member I2, preferably in theform of a metal tube or cylinder with its bottom contacting the groundor other base, and having an inverted truncated cone l6 at its upperend, ending at substantially the level of the upper ends of said sidewalls In.

A r001. I3 is formed of a plurality of segments My building may be usedas an air- I 4 of sheet metal, or other suitable material. The segmentsI4 are attached adjacent their lower ends by suitable means such asbolts I5 to the upper portions of side walls I0. Each segment is Widerat its outer portion and converges inwardly so that its-inner end issubstantially smaller. Each segment is also arched, extending inwardlyand upwardly from its outer contact with side wall I0, and thenextending downwardly and inwardly until its inner end contacts cone I6of center member I2, to which it is attached by suitablebolts I1. Theconvex roof so formed is somewhat in the shape of a doughnut cutter inappearance.

The segments I4 have side flanges I8 for overlapping the flanges ofcontiguous segments. These flanges are either U-shaped or invertedU-shaped and act to reinforce the assembled structure.

A pair of doors I9 are slidably mounted on track 20 and being curved,when opened follow the contour of the adjacent side walls It. A truss 2|attached to adjacent side walls III, extends above doors I9 to supportthe segments I4 thereabove.

Adjacent the doors I 9, because of the heavy trafiic, I have found itdesirable to provide a concrete floor 22. This flooring may, of course,be extended to cover the entire ground area or, if the ground issuitable, no flooring at all may be provided. My building may be usedfor shelter, storage, or even a home.

My circular building, being constructed of sheet metal or the like, canbe readily prefabricated and set up. There is a minimum of framework.The over-all diameter is at least twice the extent of any span used inmy construction.

When used as an airplane hangar, I surround center member I2 with tracks23 on which roll wheels 24 of turntable '25 for the rotating of saidturntable. The turntable surface is adapted to receive the spaced tailportions 26 of a plurality of airplanes 21. For those airplanes whichhave tricycle landing gears, with one of the wheels located in the nose,it is necessary to attach to the tails of such planes to my turntable,by providing a strap or rope connected to the tail of the plane andattaching it to the turntable by suitable means such as an eye 28provided therein.

An outer circular track 29 adjacent walls I0, is positioned on theground or base. On track 29 run the wheels 30 of dollies 3| on which areremovably positioned the wheels of the airplanes.

A circular spacing tube 32 is spacedly attached to dollies 3| so thatthe airplanes which are carrled by the dollies will not contact otherplanes and cause damage.

I may connect the spacing tube 32 with turntable 25 by suitable rods 33to insure that the turntable will move at the same time as the spacingtube to maintain the proper spaced relation of the airplanes at boththeir ends.

I may also provide a bracket 34 to be placed on a dolly 3| forincreasing the height of the dolly so that the wheel of an airplaneplaced upon the bracket may be raised above the other wheel of theairplane. This permits the tipping of the airplane for overlapping atthe wings, thus utilizing less space for the storage of planes andincreasing the storage capacity.

As a slightly different embodiment, I may employ, instead of a pluralityof spaced dollies, a continuous circular movable member 35 having wheels36 for movement on track 29 and having a continuous groove 31 .for thereception of the tires of the airplanes.

In use as an airplane hangar, the doors of my building may be opened bysliding them along the adjacent walls. An airplane is moved within thebuilding so that its tail is positioned onthe turntable, its wheels arepositioned on the dollies or the circular movable member, and the planeis rotated away from the door. When it is desired to remove an airplanefrom my building, I merely rotate the planes until the one desired ispositioned at the door. It can then be removed from the building.

Having thus described my invention, I claim:

1. A circular building comprising side walls having doors, a roofcooperating with said side walls, an inner turntable within saidbuilding, an

outer track within said building, a plurality of pairs of dolliesrotatable on said track, said turntable adapted to receive the tails ofthe airplanes, and said dollies adapted to receive the wheels of theairplanes for rotation of said planes to and from said doors for entryand exit of the airplanes, and a spacer ring attached to said dolliesand spacing them to space the airplanes and prevent undesired contactbetween the airplanes.

2. A'circular building as claimed in claim 1, in which the separatedollies of each pair embody wheel supporting means arranged at differentlevels with respect to said track whereby airplanes supported by theseveral pairs of dollies will each be tilted in the same direction topermit the overlapping of the wings of adjacent airplanes.
